How to Clean Nozzles
The degree at which a nozzle needs to be cleaned is dependent upon the clearance around the nozzle body and the cavity insert along with the sealing/stacking surfaces of the components. […]
How to Clean a set of hot runner system
Now we discuss the pros and cons of sending a flashed manifold out for repair versus performing this task in-house. This article will begin to deal with the disassembly, troubleshooting, cleaning and reassembling of a typical, and flashed 16-cavity valve gate manifold. […]
How to Check a hot runner system
If there is even the slightest suspicion that a manifold has flashed, the processor should put a few pellets of a red resin or contrasting colorant into the melt stream (in the nozzle tip), then shoot the mold two to four times before it’s pulled to aid in locating the source of the leak. While [...]
What is mold Cleaning?
Mold cleaning is a process where major maintenance bottlenecks often occur because molds are pulled faster than they can be cleaned and made production-ready. I have visited plants where molds waiting to be cleaned line hallways and toolrooms, taking up valuable bench space. […]
What are we meeting in the global mold market?
Global Competition Like it or not, we are all working, competing, buying and selling in a global market, and remarks made by industry regarding the unfair competition from countries with lower labor costs, favorable monetary exchange rates, tax benefits or other motivating factors are common. […]
the right surface treatment for the required mold
When one thinks of packaging a hundred images come to mind. It’s a huge and still growing industry, especially in the plastics sector where PET has become king and companies are finding it more cost-effective to produce packaging using plastic rather than aluminum or paper, for example. […]
The Copper Alloy benefit mold industry
So where are we today with the integration of copper alloys in mold building? There are still major opportunities and major contributions to be gained by companies that are willing to use these products. […]
Review the history of copper alloys in moldmaking
Prior to 1987, there was very limited use of copper alloys as molding surfaces and molds using copper alloy materials were rare. It was believed by a majority at that time that copper alloys were just not strong enough, […]
Review Copper Alloy Usage in moldmaking
During the last 20 years, copper alloy use as molding and wear surfaces in molds has been expanding although the industry has been slow in learning how to properly and fully integrate copper alloy products into their mold designs. […]
How to do a good mold cleaning
The type of fouling (chemical make-up and physical characteristics) or residue the molding process leaves behind on your tooling will help determine your cleaning requirements. Many resins contain stabilizers, […]
